Garmin Fenix 8 Pro Analysis: Built-in LTE and Orbital Communication for Phone-Free Messaging

This latest iteration of the premium Fenix outdoor timepiece introduces a life-saving feature: phone-free messaging and SOS messaging via 4G LTE or orbital links.

The Fenix 8 Pro upgrades the previously outstanding Fenix 8 by adding new cellular tech, plus an available advanced microLED display in a special edition. It is Garmin's premier model and engineered to be the single tool required to venture almost anywhere and monitor all your movements.

This makes it an extremely pricey proposition, priced from £1,030 (€1,200, $1,200, A$2,300) for the 47mm OLED model and climbing to a colossal £1,730 (€2,000/$2,000/A$3,399) for the 51mm variant with microLED screen – nearly double the cost of the standard Fenix 8.

Users get a lot of functionality for your investment, with industry-leading workout, activity and adventure tracking. Its full offline maps of the world can seamlessly direct you back to the trail if you lose your way without a phone, and look excellent on the large, sharp and super-bright touchscreen.

This Fenix 8 Pro is only offered in 47mm or 51mm case dimensions, omitting the more compact 43mm size found in other models, so it is a big watch for larger wrists. But the 47mm OLED version as reviewed does have an additional day of watch battery life despite the screen on all the time, lasting a solid eight to nine days between charges.

No-Phone Texting, Calling and Live Tracking

The company uses its own inReach LTE (4G) and satellite service plan rather than relying on a watch plan tied to your phone provider, like other wearables. However in contrast to Apple or Google's satellite-capable products, emergency communication is not provided for free.

Instead, plans begin from £7.99 or equivalent a month, which includes unlimited LTE text and audio messaging, call functionality and LiveTrack position tracking – so your contacts or loved ones can monitor you while out jogging, cycling or comparable activities – plus emergency orbital SOS alerts.

Check-ins and texts over satellite are then billed on top, with higher-tier plans including various allowances of orbital use, climbing to a £50 a month all-inclusive subscription. The watch comes with a 30-day free trial so you can test out the functionality.

Once you have got it set up, you simply venture the door minus your phone and the watch will connect to LTE. You can not use it for streaming music or similar tasks, but you can place and receive calls, dispatch texts and generally stay connected with your family and companions.

Whenever you message someone, Garmin sends them an SMS from a arbitrary number, which they can respond to directly to your watch. If they download the Garmin Messenger app, you can then message back and forth via typed or voice communications, and initiate voice calls. Your recipient does not need a Garmin profile to use the Messenger application, just a phone number is sufficient to register for texts.

Texting on the watch functions adequately but composing texts on the tiny on-screen keyboard is slow. It has a set of customisable pre-set responses you can use to speed things up. Voice recordings and calls work OK, though as with most smartwatches, you’re unlikely going to wish to use it for extended conversations as the quality is not fantastic.

LiveTrack is the most useful feature. You can set it up to automatically transmit a link to selected contacts every time you start an activity, so they can track your real time position on a map. It’s great for monitoring competition progress, but it primarily serves as a tool for someone you rely on to know your location in case an incident occurs. It has generally worked effectively, although the actual position has sometimes lagged when transitioning in and out of good LTE signal.

These features are accessible on other Garmin watches if you carry your phone with you, but in areas where LTE lacks coverage, the orbital activates on the Fenix 8 Pro to transmit texts, position updates and emergency SOS.

A guide shows you how to find the line of sight to the satellite, which then transmits and gets communications within about 10 to 30 seconds. It was unexpectedly straightforward to use and could be a crucial safety feature, though it is essential to remember that orbital coverage is restricted to the US continent, most of Canada, and most of Europe excluding parts of Scandinavia above 65 degrees north.

Environmental Impact

The watch is generally repairable with services offered via the customer service portal. The battery is rated to maintain at least 90% of its original power after two years of regular charging. The watch does not contain any recycled components. Garmin provides disposal programs on recent purchases.

Cost

The Fenix 8 Pro is priced from £1,029.99 (€1,199.99/$1,199.99/A$2,299). The optional Garmin inReach subscription plans begin from £7.99 (€9.99/$7.99/A$13.50).

Conclusion

The Fenix 8 Pro builds on a excellent outdoor watch in the regular Fenix 8 and incorporates LTE for texting, calls and LiveTrack – plus orbital messaging, check-in and emergency SOS for when you’re without coverage.

Outcome is an even more impressive outdoor tool for those that desire to be phone-free. If you want to have someone monitor you from afar while running out at night or in the middle of nowhere, the Garmin accomplishes this without needing additional gear.

This is very freeing to be outside without a phone, but that capability comes at quite a cost, both in terms of the substantial cost of the watch and the monthly fee of the inReach plan to enable the service. Fortunately it isn’t dependent on your phone provider so works with all make of smartphone and network.

This Fenix 8 Pro is a killer device for someone who dislikes being burdened by their phone when jogging, biking or hiking, but still desires to be trackable and contactable. For other users, it is a significant money when the superb Fenix 8 already exists.

Advantages: LTE and orbital communication, high-luminance OLED display, monitors everything with best-in-class GPS, integrated flashlight, voice and offline commands, 8+ day endurance, Garmin Pay, full offline maps and routes, offline Spotify, 100-metre water resistance and 40-metre diving, buttons and touch.

Cons: extremely costly, LTE and orbital features require monthly payment, restricted Garmin Pay bank compatibility, voice features are slow, basic wearable features versus Apple/Google/Samsung watches.
